我已经设置了我的邮件服务器与SMTP和Dovecot IMAP的Postfix。 而不是虚拟用户，我只是倾听来自Server Fault的人的build议，并与Linux用户一起。 我使用RainLoop作为networking邮件服务。 我configuration了SPF，为了让我的电子邮件到达其他提供者，我必须使用身份validation。
所以我（试图）设置TLS来处理我使用Let's Encrypt客户端获得的SSL证书。 以下是我的main.cf文件：

以下是我的master.cf文件：

我基本上只是启用了sumbission 。
RainLoop连接到我的IMAP服务器和SMTP服务器：

只要“使用validation”被禁用，或者如果我使用PHP mail(); function，我可以发送电子邮件，并在任何地方接收。 他们被标记为垃圾邮件，所以我想我需要启用身份validation，但如果我这样做; 我无法发送电子邮件，这是从我的mail.log文件：
# i replaced my server's public ip address with 127.0.0.1 Jun 23 05:14:57 mailserver dovecot: imap-login: Login: user=<shavit>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=16305, TLS, session=<QVtwdek15swlOzfP> Jun 23 05:14:57 mailserver postfix/smtpd[16306]: connect from mydomain.co.il[127.0.0.1] Jun 23 05:14:57 mailserver postfix/smtpd[16306]: Anonymous TLS connection established from mydomain.co.il[127.0.0.1]: TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Jun 23 05:14:57 mailserver postfix/smtpd[16306]: warning: mydomain.co.il[127.0.0.1]: SASL CRAM-MD5 authentication failed: authentication failure Jun 23 05:14:57 mailserver postfix/smtpd[16306]: disconnect from mydomain.co.il[127.0.0.1] ehlo=2 starttls=1 auth=0/1 quit=1 commands=4/5 Jun 23 05:14:57 mailserver dovecot: imap(shavit): Logged out in=11 out=401 Jun 23 05:14:57 mailserver dovecot: imap-login: Login: user=<shavit>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=16310, TLS, session=<BsR2dek16MwlOzfP> Jun 23 05:14:57 mailserver dovecot: imap(shavit): Logged out in=90 out=884
我的SSL证书是有效的; 我使用nginx的5个虚拟主机在同一个域下，他们都工作，所以这个选项可以消除。
我做错了什么，或者; 我将如何解决它？ 帮助将不胜感激！
TLSconfiguration可能是一个红鲱鱼。 SASL CRAM-MD5是非典型的。 也许你想要SASL PLAIN或SASL LOGIN 。 由于您正在使用dovecot进行IMAP，因此您可能还想使用dovecot的sasl提供程序进行postfix。 http://www.postfix.org/SASL_README.html#server_dovecot
